Normal corneal thickness, peripheral 1 mm, center 0.5 mm, if it reaches the above value, myopia surgery can be done. Corneal laser ablation can be considered when the corneal thickness is greater than 350um, but there is no clear requirement for corneal thickness in ICL surgery. There are two kinds of myopia surgery, one is corneal laser cutting surgery and the other is tear refractive surgery. Laser ablation surgery requires myopia less than 900 degrees, astigmatism less than 400 degrees, corneal thickness greater than 350um, ICL surgery degree limited to 300-2300 degrees, astigmatism less than 600 degrees. Myopia surgery age 18 to 40 years old, that is, myopia surgery will be considered after the degree is stable. At present, myopia surgery technology is relatively mature, and the problem is not big. Just improve the preoperative examination and cooperate with the doctor. Looking for China Vision Ophthalmology for myopia surgery, as the Jinan Branch of Huaxia Ophthalmology Hospital, under the leadership of Director Wang Lihua for many years, we have strictly followed the principles of precise technology and safe operation, made continuous progress, and strived to do all kinds of ophthalmology operations well. Learn more.
The principle of myopia surgery is to change the diopter of cornea. Be sure to evaluate the condition of cornea before operation, especially the thickness of cornea. Only when the corneal thickness reaches the normal range can corneal refractive surgery be performed. The thickness of cornea is evaluated according to the average thickness of normal cornea. The average central thickness of normal people is 0.5 mm and the peripheral thickness is1mm. After reaching the above standard values, corneal refractive surgery, that is, myopia surgery, can be considered. If you don't want glasses, it's better to find China Vision Ophthalmology, so you don't need glasses in your life. In order to achieve this goal, China Vision Ophthalmology has been exploring various ophthalmic problems, from laser surgery to lens surgery, from ordinary laser surgery to femtosecond laser surgery, from myopia, hyperopia, astigmatism, children's oblique amblyopia, cataract and so on.
